DEEP-BORING- APARATUS.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application led April 26, 1907. Serial No. 370,481.

To all whom it may concern:

Be it known that I, IILHELM SCHOTT, a subject of the King of Prussia, and resident of Erkelenz, in the Province ot the Rhine, German Empire, manager, have invented certain new and useful Improvements in Deep-Boring Apparatus, of which the following is an exact specification.

This invention relates to deep boring apparatus for use in mining and prospecting and comprises a device, in which a boring tool is operated by a lever connected to a pivoted beam, adapted to be counter-loaded, so as to compensate for the increased length ot' the boring tool and also adapted to have its fulcrum altered so to alter the extent of reciprocations ot the boring tool.

The accompanying drawings illustrate this invention, and in these drawings:

Figure 1 is a sectional side view of a deep boring apparatus in accordance with this invention the crank shaft bearings being omitted in this figure. F ig. Q is an end view ot the same.

In carrying this invention into eiiect according to the form shown, a boring beam or swipe a is mounted in a pivot d', which is supported on a cross block e, which in the form shown is made of wood. rIhe cross block e is in turn supported on springs z' resting on a cross block f. This cross block j is provided on its underside with a bracket g2, carrying the pivot ot a connecting rod g, the other end ot which is connected to a crank g which is caused to rotate by any suitable motor (not shown). Below the cross piece j" there is provided a further cross piece 7i which is connected to the cross piece f by springs z". The cross piece L rests on a frame (Z which forms the traine of the machine. The beam or swipe a is connected on either side of its pivot CZ by means of rods ft and c with a pivoted beam L. These connecting` rods l': and c are preferably provided with turn buckles Q, by which the length of these rods may be adjusted.

In order to enable a relative movement of the beams a and t the rod c, which is pivoted at a to the rod a., is at its opposite end c2 pivoted to a bracket a connected by bolts n. to the beam b, springs o being interposed between the bracket n and the beam to permit of the relative movement mentioned above. The beam b is pivoted about the point and, as can readily be seen from the drawings, this pivoting point is adjustable. Thus to the underside of the beam b there is iixed a bearing plate b2 provided with notches b4, any one of which may be made to rest on the pivoting roller Z9 which is mounted on a suitable part b5 of the frame (l. On the short arm of the lever a, that is on the lett hand side of said lever, there is mounted the rod s which carries the boring tool. -It will be understood that as t-he depth of the boring increases the length ot the rod also increases and theretore its weight. According to the present invention this increased weight of the boring rod s is counter balanced by means of balance weights m placed on the long arm [of the lever b.

i The operation ot this device will be self evident. It will be seen that when the crank f/ rotates the lever a is reciprocated through the spring connection z' and z". In this way the balance lever b is oscillated about its pivot and the extent of this oscillation can be controlled by altering the pivoting point ZJ of the lever This adjustment of the pivoting point oit' the lever in conjunction with the spring connection 0 allows the boring beam or swipe a to be given a variable movement, and as will be readily understood the driving connections are all resilient, whereby a resilient pressure is exerted on the boring tool s.

According to this invention it will be seen that it is unnecessary to change the cranks g when it is desired to alter the reciprocations of the rod s, and in fact, that the reciprocations of the rod s can be adjusted to suit the requirements of the ground through which the boring is to be made, while at the same time by means of the spring driving connection ot the rod s the requirements of each individual stroke are also met and damage to the parts of the machine thereby avoided.

Having thus fully described the nature oi my said invention, what I desire to secure by Letters Patent ot' the United States is 1. A deep boring apparatus comprising in combination with a boring tool a pivoted beam carrying said tool means for reciprocating the pivot of said beam, a pivoted balancing beam resiliently connected to said boring beam.

2. A deep boring apparatus comprising in in combination With the boring tool, a beam carrying said tool, means for reciprocating said beam and a pivoted balance beamresiliently connected to said tool carrying beam,

the pivoting point of said balance beam being adjustable.

4. A deep boring apparatus comprising in combination with the boring tool a beam carrying said tool, means for reciprocating said beam, a pivoted balance beam resiliently connected to said .tool carrying beam, the pivoting point of said balance beam being adjustable, and counterbalancing means on said balanced beam for the boring tool.

A deep boring apparatus having in combination with a boring rod a boring beam, a reciprocating resiliently mounted fulcrum for said beam, a balance beam, an adjustable fulcrum for said balance beam, connecting means for said beams, said connecting means permitting relative movement of the beams.

6. A deep boring apparatus having in combination With a boring rod a boring beam, a resilient pivot for said boring beam, spring driving means for reciprocating said pivot, a balance beam, connecting means for said beams, said connecting means permitting relative movement of the beams, counter balance means for the boring tool on said balance beam.

7. A deep boring apparatus having in combination with a boring rod a boring beam, a pivot for said boring beam, spring mounted cross bars supporting said pivots, means for reciprocating said cross bars, a supporting frame, a balance beam supported by said frame, adjustable pivot means for said balance beam, an adjustable connection at one end of said balance beam to said boring beam, an adjustable and spring connection from the opposite end of said balance beam to said boring beam, counter balance Weights on said beam for tbe boring tool.
